Presbyopia is a refractive error that makes it challenging for middle-aged and older persons to see details up close. It occurs as a result of the lens’ (an inner eye component that aids in eye focus) failure to properly concentrate light on the retina (a light-sensitive layer of tissue at the back of the eye).…
Read MoreWhen the sixth cranial nerve, (also known as the abducens nerve) is injured or malfunctions, it becomes difficult to move the eyes in certain directions. The lateral rectus muscle of the eye receives signals from the sixth cranial nerve and enables the eye to move in a lateral direction. Each lateral rectus muscle in each…
Read MoreInfants who are premature (born early) or who weigh less than 3 pounds at birth may develop retinopathy of prematurity (ROP). Infants who have received oxygen therapy, developed infections or faced additional health issues associated with preterm birth are at greater risk of developing ROP. ROP occurs when aberrant blood vessels develop in the retina…
Read MoreDouble vision, or diplopia, is when a single object appears to be in two different ways when looking at it.Double vision is typically a transient problem. However, it can sometimes be a symptom of a more serious, underlying medical issue. Hence, it is important that any changes in your eyesight be tested right away. Diplopia…
Read MoreA condition known as glaucoma affects the optic nerve permanently and eventually leads to “Tunnel Vision.” Glaucoma is brought on by an increase in ocular pressure brought on by the drainage channel’s obstruction. A kind of secondary open-angle glaucoma known as pigmentary glaucoma is characterised by pigment that leaks from the iris and obstructs the…
Read MoreIndividuals suffering from thyroid disease may at times develop thyroid disease. Occasionally, symptoms of thyroid eye disease may be the precursor in diagnosing any underlying thyroid disease. According to research, an autoimmune condition is the root cause of thyroid disease and thyroid eye disease. Immune system imbalance or recognition issue occurs. Our immune systems typically…
Read MoreRetinal detachment (RD) occurs when the thin layer of tissue, known as the retina, containing photoreceptors, in the back of the eye pulls away from its normal position. Retinal detachment is an ocular emergency as the longer the retina remains detached, the higher are the risks of losing vision permanently. Indicators of RD include an…

Read MoreWith the recent increase in dengue cases it is important to be aware of its effect on the eye. The dengue virus can cause various eye manifestations including subconjunctival haemorrhage, macular chorioretinitis, macular oedema, dengue related optic neuritis, retinal haemorrhage, vitritis, and anterior uveitis. Subconjunctival haemorrhage is a small bleed behind the conjunctiva. The conjunctiva…
Read MorePellucid Marginal Degeneration (PMD) is a chronic, slowly progressing condition that causes peripheral corneal thinning. The cornea is the dome shaped, transparent window in the front of the eye. It is crucial to recognise PMD because it may result in a serious decline in visual function. Additionally, refractive surgery patients with PMD may experience negative…
