PURPOSE:: 1) To evaluate factors governing flow of subretinal fluid and validate Lincoff rules (LRs) in cases of rhegmatogenous retinal detachment. 2) To identify cases of rhegmatogenous retinal detachment where LRs are not followed. METHOD:: This was a retrospective study where 253 patients of rhegmatogenous retinal detachment were identified through surgery records. Two hundred and twenty-nine case sheets with complete record of ocular examination and surgical findings were analyzed. Seventy-five of the 229 patients, having subtotal rhegmatogenous retinal detachment where LR could be applied were included for analysis. Validity of LR was analyzed about location of break, lattice degeneration, posterior vitreous detachment (PVD), proliferative vitreoretinopathy, lens status, myopia, and trauma. RESULT:: The mean age of the patients was 40.12 years. Sixty-one were men. Lincoff rule was validated in 59 of the 75 patients. Anterior breaks (P < 0.008) and PVD (P < 0.001) were found to have a significant association with validity of LR. Other attributes did not have a statistically significant association with validity of LR. CONCLUSION:: Presence of posterior retinal breaks and absent PVD is associated with unusual flow of subretinal fluid. Lincoff rules are valid in most of the clinical scenarios.
