AGE RELATED MACULAR DEGENERATION (ARMD) The macula is the part of the retina, which provides us central vision and allows us to see fine detail, such as recognizing a face, reading, or watching television. Macular Degeneration is a condition in which the macula gets damaged. It is often related to aging, and is commonly referred to as Age-related Macular Degeneration (AMD). The late stage, associated with vision loss, is the most common cause of irreversible blindness in people over the age of 50. It affects the central vision, especially while reading. Most often vision loss starts in one eye. Because the healthy eye compensates for the loss of vision in the damaged eye, Macular Degeneration may initially go unnoticed. In many cases it will ultimately affect vision in the other eye as well. What are the types of Age-related Macular Degeneration (AMD)? Dry AMD: The retina becomes thinner (atrophic) and stops functioning. This may cause some people to detect "blank" areas in their central vision. The vision loss due to this Dry AMD is not very severe as compared to the Wet AMD. While there is no treatment available for people with Dry AMD, various low vision aids are available to help these people see well and perform daily activities. Wet AMD: Abnormal blood vessels grow under the macula. These abnormal vessels leak fluid and blood, and thus cause swelling and scar tissue formation, leading to distorted vision and severe vision loss. Why is Early Detection important? The vision lost due to AMD is generally irreversible, and the treatment methods try to preserve vision but may not improve vision. Hence it is important to detect this disease at an early stage, before it has caused significant vision loss. How is Macular Degeneration or AMD detected? In the early stages of AMD, a person's vision may become blurred or distorted. A retinal examination, with the help of special tests like Fluorescein Angiography, OCT etc. can help the eye specialist to diagnose the condition. Since many times the patient may not notice the initial distortion or blurring of vision, the key to preventing vision loss due to AMD is regular eye examinations for patients above 40 years of age. These regular checkups are also useful in detecting other potentially serious diseases like Glaucoma. What are the Treatments available? Untreated, AMD is known to progress and lead to further loss of vision, the rate of deterioration being faster in the wet type. Antioxidants and Multivitamin capsules may have a role in preventing or decreasing the speed of progression of the disease. In Wet AMD, additional methods of treatment are required to arrest or at least retard the progression of the disease. There have been many exciting developments in the treatment of Wet AMD with better results now. The best-suited treatment modality is decided by the eye specialist after discussing with the patient. The most popular and established modes of treatment are: Intravitreal Injections: This is the exciting new development in which certain special medicines like anti-VEGF agents (Lucentis/Accentrix/Razumab, Eylea, Avastin etc.) are injected in small quantities within the eye to arrest the disease. The success rate for maintaining the vision is as high as 90% and in about 30% of cases, there is even an improvement of vision. However, the effect of these injections is not permanent and generally repeated injections (at 4- 6 weeks interval) may be required. Conventional Laser: Burns the abnormal blood vessels and thus stops the leakage. However, since it also damages the normal retina structures, it may itself lead to decreased vision. Hence, it is suitable only in selected cases where the new vessels are not very close to the central macular area.

RETINAL DETACHMENT What Is Retinal Detachment? Retinal detachment is a serious eye condition where the retina pulls away from the back of the eye. The retina is a thin layer of nerve tissue that lines the inside of the eye and sends visual signals to the brain. If it detaches, it can no longer work properly — leading to vision loss if not treated quickly. Why Is It Serious? If not treated right away, retinal detachment can lead to: Permanent vision loss Partial or total blindness in the affected eye Symptoms of Retinal Detachment See an eye doctor immediately if you notice: Sudden flashes of light (like lightning streaks) A sudden increase in floaters (tiny spots or strings that move in your vision) A dark shadow or curtain over part of your vision Blurry or distorted vision Reduced side (peripheral) vision These symptoms are often painless but require urgent care. Causes and Risk Factors Retinal detachment can happen due to: 1. Tears or Holes in the Retina Often related to aging or lattice degeneration 2. Traction Scar tissue or pulling from inside the eye (common in people with diabetic eye disease) 3. Fluid Build-up Fluid leaks under the retina, pushing it away Risk Factors: Nearsightedness (myopia) Previous eye surgery (like cataract surgery) Eye trauma Family history of retinal detachment Lattice degeneration Aging (more common after age 50) Diagnosis An eye doctor will perform a dilated eye exam to look at your retina. Additional tests may include: OCT (Optical Coherence Tomography) Ultrasound imaging (if there's bleeding) Treatment Options Retinal detachment usually needs surgery as soon as possible. Common procedures include: 1. Laser or Cryotherapy Seals small tears before they lead to detachment 2. Pneumatic Retinopexy A gas bubble is injected into the eye to push the retina back in place 3. Scleral Buckle A silicone band is placed around the eye to relieve pulling on the retina 4. Vitrectomy Removes the gel (vitreous) pulling on the retina and replaces it with a gas or oil bubble Your doctor will recommend the best treatment based on your specific case. Recovery Vision may improve gradually after surgery Some vision loss may be permanent if detachment was severe or prolonged Avoid heavy lifting and strenuous activity during healing Follow-up appointments are crucial Can It Be Prevented? You can’t always prevent retinal detachment, but you can lower your risk by: Getting regular eye exams, especially if you're nearsighted or have a family history Seeing an eye doctor immediately if you have symptoms Protecting your eyes from injury Managing diabetes and other health conditions

SQUINT & PAEDIATRICS 🧑⚕️ What Is a Squint? A squint, also called strabismus, is a condition where the eyes do not look in the same direction. One eye may turn inwards, outwards, upwards, or downwards while the other looks straight ahead. It can happen all the time or only some of the time (intermittently). 👶 Who Gets It? Babies and children (most common) Adults (due to injury, stroke, nerve problems, or eye conditions) 🧠 Causes Poor eye muscle control Nerve problems Refractive errors (need for glasses) Genetic/family history Eye injuries or conditions Neurological conditions 👁️ Symptoms Eyes appear misaligned Double vision Closing or covering one eye to see better Tilting the head to one side Poor depth perception In children: may lead to lazy eye (amblyopia) 🧪 Diagnosis An eye specialist (optometrist or ophthalmologist) will: Examine eye alignment Test vision in both eyes Check eye movement 💊 Treatment Options for Squint Treatment depends on the type, cause, age of the patient, and severity. 1. Glasses Correct refractive errors May help align the eyes, especially in accommodative squint 2. Eye Exercises (Orthoptics) Improve coordination and focus in mild cases Often used with other treatments 3. Patching (Occlusion Therapy) Used for amblyopia (lazy eye) Involves covering the stronger eye to strengthen the weaker one 4. Prism Glasses Help reduce double vision Can help realign vision in small-angle squints 5. Surgery To correct the position of eye muscles Common and often successful May be done in children or adults Multiple surgeries may be needed in some cases 👨👩👧 Support for Parents Early diagnosis is important to avoid long-term vision problems like amblyopia. Squints are treatable, especially if caught early.

Retinopathy of Prematurity (ROP) Screening 🍼 What is Retinopathy of Prematurity (ROP)? ROP is a potentially blinding eye disease that affects premature babies. It happens when abnormal blood vessels grow in the retina (the light-sensitive layer at the back of the eye). Early detection and treatment can prevent vision loss or blindness. 📋 Why Is ROP Screening Important? In India, many babies are born premature or with low birth weight, putting them at high risk of ROP. ROP usually shows no early symptoms, so screening is the only way to detect it. Timely screening and treatment can save your baby’s eyesight. 👶 Which Babies Need ROP Screening (as per Indian Guidelines)? ROP screening is recommended for: Babies with: Birth weight less than 2000 grams Gestational age less than 34 weeks Also, some babies above these limits may be at risk and should be screened if they: Received oxygen therapy for more than 5 days Had serious problems like sepsis, blood transfusions, breathing issues, or poor weight gain The neonatologist or pediatrician will decide if your baby needs screening. 🕒 When Should the First Screening Be Done? For babies born before 28 weeks or weighing under 1200 grams: by 2–3 weeks after birth For others: by 4 weeks after birth Never delay the first screening, even if the baby still seems small or unwell. 👁️ How Is the ROP Screening Done? An eye doctor (ophthalmologist) who is trained in ROP checks your baby’s eyes. Eye drops are used to dilate (enlarge) the pupils. The doctor uses a special instrument to examine the retina. The procedure takes a few minutes and may cause brief discomfort, but it is safe. Do not feed the baby for 30 minutes before examination, ✅ What If ROP Is Found? Mild ROP often improves on its own and just needs monitoring. Severe ROP may need treatment to prevent blindness. Treatment options include: Laser therapy Anti-VEGF injections Surgery (rarely) 📆 What About Follow-Up Visits? Regular follow-ups are needed until: The retina is fully developed Or the ROP has resolved/stabilized Even if the first screening is normal, repeat exams are often needed. 🏥 What Should Parents Do? Ensure screening is done on time – usually in the NICU or by referral. Keep all follow-up appointments, even after the baby goes home. Ask the doctor: “Has my baby had an ROP screening?” “When is the next eye checkup due?”
