Figure 1 Representative echographic features of (A) dense vitreous opacities with retinal and choroidal detachment, (B) marked vitreous membranes, (C) retinal detachment with retinal opacities, and (D) choroidal detachment (with retinal opacities).

Figure 2 Advanced echographic features among culture-negative, coagulase-negative staphylococci, and other culture-positive endophthalmitis. Percentage of dense vitreous opacities (A), marked vitreous membranes (B), retinal detachment (C), and choroidal detachment (D) in culture-negative endophthalmitis cases, in coagulase-negative staphylococci, and other culture-positive endophthalmitis cases.

Abbreviation: coag neg staph spp, coagulase-negative staphylococci.

Table 2 Echographic features in culture-negative, coagulase-negative staphylococci, and other culture-positive endophthalmitis; percentage of dense, moderate, and mild vitreous opacities, marked, moderate, and mild vitreous membranes, posterior vitreous detachment, retinal detachment, and choroidal detachment in culture-negative, coagulase-negative staphylococci, and other culture-positive endophthalmitis

	Vitreous opacities (%)				Vitreous membranes (%)				PVD (%)	Retinal detachment (%)	Choroidal detachment (%)
	Dense	Morderate	Mild	None	Marked	Moderate	Mild	None
Culture negative (n = 60)	43.3	43.3	13.3	0.0	41.7	33.3	10.0	15.0	21.7	35.0	18.3

	Mean final visual acuity	Median final visual acuity
Culture negative	2/200 to 1/200	HM to LP
Coagulase negative staphylococci	8/200	20/400
Culture positive	2/200 to 1/200	HM

Abbreviations: HM, hand motion; LP, light perception.

Notes: Statistically significant difference in final visual acuity (logMAR) in cases with dense as compared with moderate or mild vitreous opacities, marked as compared with moderate, mild, or no vitreous membranes, with and without retinal detachment, and with and without choroidal detachment.
Abbreviations: VA, visual acuity; VO, vitreous opacities; VM, vitreous membranes; RD, retinal detachment; CD, choroidal detachment.
