Abstract Details


Cataract surgery is the commonest ocular surgery performed. Preoperative ocular assessment routinely includes examination of visual acuity, intraocular pressure, patency test of nasolacrimal passage, visual axes alignment, lens�â�€�™ position and fundoscopy to evaluate optic disc and macula. This study details the peripheral retinal lesions detected pre- and post-operatively in cataract patients and emphasize the importance of pre- and post-operative peripheral retinal examination.


The study was conducted at Disha Eye Hospitals,a tertiary eye care centre in West Bengal, India.


119 patients who underwent cataract surgery by phacoemulsification and required intervention for peripheral retinal lesions were included in this study. Retrospective study of the clinical records was done, to determine at which stage of treatment timeline and what led to the diagnosis of peripheral retinal lesion.


The patients were in the age group of 31 to 74 years with mean age of 57.9 years. Male: female ratio was 1.5 :1.In 71% cases (84/119) retinal lesion was detected in the preoperative period and in rest (35/119) after surgery.The diagnosis was done by performing pre-operative indirect ophthalmoscopy. In the post-operative diagnosis group 72% of patients had complained of flashes or floaters or both. In this group one patient had mature cataract, six had grade IV nuclear sclerosis.Overall retinal lattice with holes was seen in 69% of patients. Retinal barrage laser was done in 113 cases.


Peripheral retinal examination by indirect ophthalmoscopy should be performed all cataract cases preoperatively except where it is not possible like mature cataract, black cataract or complicated cataract with seclusio papillae.Preoperative barrage laser in symptomatic patients, should always be performed. Post-operative peripheral retinal examination should also be performed during first follow-up visit particularly following surgery in mature cataracts, myopic eyes,or complicated surgery.All complaints of post-operative floaters and flashes should receive immediate attention and peripheral retinal examination should be performed.
