Purpose	We aim to describe the clinical profile of patients with posterior scleritis who misdiagnosis as some other entities.
Methods	Retrospective chart analysis of patients with posterior scleritis visiting a tertiary eye care institute from January 2010 to June 2022
Results	A total of 56 eyes of 48 cases of posterior scleritis were included and mean age of presentation was 17.5 years (11-73 years). Thirty eyes of 27 patients were initially misdiagnosed as some other entity other than posterior scleritis. Most common causes of misdiagnoses were optic neuritis (16.6%), Vogt Koyanagi Harada disease (10%) and choroidal tumour (10%) and orbital cellulitis (10%). The most common reason for misdiagnosis was absence of ocular pain on presentation (17 cases). Others were restricted extraocular movements, periorbital oedema, optic disc oedema with subtle subretinal fluid , missed normal pupillary reflex, and misleading neuroimaging features suggesting cellulitis. Seventeen eyes (30%) had concurrent anterior scleritis. Most common systemic association in these patients was tuberculosis. Twenty-one patients (43.75%) developed recurrence of posterior scleritis. Mean visual acuity (LogMAR) on presentation was 0.42 ± 0.50 and improved to 0.16 ± 0.39 on final follow-up.
Conclusion	Posterior scleritis has a plethora of clinical manifestations and is prone to misdiagnosis. In India, tuberculosis can be an important cause of posterior scleritis
