Indications and Results of Relaxing Retinotomy

Functional outcome and prognostic factors in 304 eyes managed by retinectomy

“…Retinectomy is a useful surgical technique in the management of complex retinal detachments with PVR when other procedures including membrane peeling and scleral buckling are inadequate [10,14,20,21,[27][28][29]31]. It is usually reserved for cases with advanced PVR although it may occasionally be useful for localized, less severe, pathology, for example, where there is retinal incarceration and localized PVR following trauma.…”

“…This may involve extensive membrane peeling, scleral buckling and gas or silicone oil tamponade, and in certain situations, relaxing retinotomy or retinectomy is necessary to alleviate residual traction to the anterior and/or posterior retina [10,14,20,21,[27][28][29]31]. Since first described in 1979 [27], retinectomy is generally reserved for the management of severe cases of PVR and occasional cases of advanced PDR.…”

Outcomes of Retinectomy of 180° or more in Retinal Detachment with Advanced Proliferative Vitreoretinopathy

“…Various studies have reported that extent of retinectomy and the preoperative VA (albeit as surrogate markers of disease severity) are directly related to final VA. 2,3,24 Some reports, however, did not find any association between extent and location of retinectomy and visual prognosis. 1,8 In our study, 51.2% eyes showed improvement, 25.6% eyes maintained, while 23.2% eyes had deterioration from their presenting visual acquity.…”

“…traumatic retinal incarcerations, tractional retinal detachments in vasoproliferative vasculitides, acute retinal necrosis, etc). [1][2][3][4][5]7,9 Further, we found that grades and extent of PVR were either not clearly specified (only stated as advanced PVR) 6 or there was a heterogeneous selection of cases as far as grading of PVR was concerned (PVR C-D, 4 subretinal fibrosis, 5 anterior PVR). [3][4][5] Few authors have made no mention regarding the size of retinectomy, 4,5 while still others have presented combined results of cases with varying sizes of retinectomies.…”

“…1 In addition to complex PVR, retinectomies have been attempted in conditions such as high myopia with loss of retinal elasticity, proliferative vasculopathies like diabetic retinopathy, penetrating trauma, particularly in presence of retinal incarceration and large subretinal proliferations. [1][2][3] Several published reports have presented results of retinectomy for complex retinal detachments (RD) with variable rates of anatomic reattachment (14-80%). [3][4][5][6][7][8][9] Reported favorable outcomes of this technique include retinal reattachment, improvement or stabilization in visual acuity, regaining of ambulatory vision and visual field, etc.…”
