“…However, in the rest of the cases, the cause of MPP remains un certain. Havener [2] found MPP in 12.7% of retinal detachment cases, but the present study showed a low incidence of MPP, only 3.5% of the cases of idiopathic retinal de tachment. The present study shows a close relationship between MPP and the diabetic state, although only a small number of cases of MPP were analyzed.…”

“…MPP has been considered to be a pro gressive shrinkage of the collagenous frame work of the vitreous or contraction of the epiretinal fibrous tissue which proliferates upon the retinal surface [1,2]. Tolentino et al [10] thought that the cortical layer of the vitreous forms a membrane bridging the anterior and posterior sections leading to a connective tissue ring in front of the optic disc with progressive shrinkage of the vitre ous.…”

The relationship between the ‘diabetic state’ and massive periretinal proliferation (MPP) in idiopathic retinal detachment was examined. In 18 (3.5%) of 508 cases of idiopathic retinal detachment, MPP occurred before or after retinal detachment surgery. In 24 cases of retinal detachment, a diabetic or suspected diabetic state was found. 11 of the 24 were receiving treatment for diabetes and never developed MPP, while 5 of the 13 patients who were not being treated had MPP. This suggests that MPP in retinal detachment may easily be induced by the diabetic state and prevented by treatment for diabetes. Additional causes of MPP in retinal detachment were giant tears, massive vitreous hemorrhages at operation and frequent recurrence.

SUMMARY Seventy-five cases of total retinal detachment complicated by the more advanced grades (grades C and D) of proliferative vitreoretinopathy were treated with scieral buckling, vitrectomy, and air-fluid exchange. The overall reattachment rate was 56%, ranging from 100% in grade C-1 to 26% in grade D-3. The postoperative visual acuity was 6/120 or better in 48% of the 42 eyes in which the retina was reattached. The major causes of surgical failure were redetachment from persistent vitreoretinal traction (32%) and intraoperative complications (12%).

“…Just as the name implies, shrinkage of vitreous alone was originally thought to be the cause of massive vitreous retraction (MVR). Havener (1973) in a rather recent detailed article describing MVR still adheres to this theory. Interestingly, he speculates that anterior vitreous separates from the vitreous base, which retracts posteriorly and forms a frontal plane.…”

“…Many workers have thought in the past, and most recently (Havener, 1973;Algvere and Kock, 1976) that this collagen formation is the key to the contraction of these membranes. However, mainly the collagen component that makes the intravitreal tissue look whitish and forms the relatively solid intravitreal membranes (Fig.…”
