Complications associated with rigid contact lenses are more frequent in aphakia. The limited dexterity of older patients not only may prove an insurmountable barrier to the mastery of daily contact lens insertion and removal, but also may produce significant direct eye trauma, its seriousness determined by the integrity of the cataract wound. Since prolonged wear of aphakic contact lenses is the rule rather than the exception, the risk of irreversible corneal changes such as vascularization and erosions is greater. A poorly fitted aphakic contact lens that does not permit adequate oxygenation of all corneal areas makes such complications even more likely to occur. Decreased corneal sensitivity associated with cataract surgery permits continued wear of a poorly fitted lens, which does not allow the cornea to recover between wearing periods. Detection of keratoconjunctivitis sicca, more prevalent in the older age group, may prevent the associated complications of corneal erosion, iritis, and infection. Complications of aphakic contact lenses can be controlled by patient instruction, appropriate contact lens adjustments, and regularly scheduled follow-up examinations.

In a study of 112 patients (49 men, 63 women) with psoriatic arthritis, ocular inflammation was noted in 35 (31.2%). Conjunctivitis was the most common lesion, being found in 19.6% (10 males, 12 females). Iritis occurred in 7.1% (5 men, 3 women), episcleritis in 1.8% (1 man, 1 woman), and keratoconjunctivitis sicca in 2.7% (3 women). 20 patients (10 men, 10 women) had radiological sacroiliitis and 11 of these (7 men, 4 women) had ankylosing spondylitis according to the New York criteria. Eye lesions were noted in 7 of the patients with sacroiliitis, 3 having iritis (15%) and 4 (20%) conjunctivitis. 2 patients with spondylitis had iritis (18%) and 1 (9%) conjunctivitis. It is concluded that inflammatory eye lesions are a frequent accompaniment to psoriatic arthritis. This is taken as further evidence for the concept of the seronegative spondyloarthritides.

Recent work has shown changes in the corneal endothelium accompanying corneal epithelial disease and anterior uveitis. It is important to differentiate these acute changes from other changes such as guttatae or corneal pigment deposition and to assess the magnitude of their effect upon the corneal endothelium. We have used specular microscopy to study changes in the corneal endothelium and Descemet's membrane and to study deposits on the back of the corneal endothelium and correlate them with changes in the endothelium by the use of conventional specular microscopy and by relief images which give a three dimensional view of the area concerned. This has particularly been applied to the conditions of superficial punctate keratopathy, keratoconjunctivitis sicca, corneal abrasions and exposure keratopathy, iritis and cyclitis, pseudoexfoliation of the lens capsule, anterior segment pigment dispersal syndrome, bullous keratopathy as well as corneal guttatae and pigment granules on the posterior cornea. Preendothelial lesions have been distinguished from endothelial and retrocorneal lesions by this technique aiding elucidation of the state of the endothelium. The changes which we noted occurred either at the level of Descemet's membrane (including formation of small rounded dark blebs less than one cell in diameter, larger blebs one to three cells in diameter, and guttatae, usually larger than the foregoing and sometimes very numerous), or at the level of the posterior endothelial surface (including small shiny nodular deposits, often numerous, due to pigment granules, and keratitic precipitates and inflammatory debris, the former usually large and the latter smaller, more irregular and sometimes very numerous). The differentiation and assessment of these various changes are discussed.

Idiopathic orbital inflammatory syndrome (IOIS) is a nonspecific inflammation of orbital tissue. As it is a diagnosis of exclusion, systemic testing and, at times biopsy, is utilized to rule out other inflammatory etiologies. Since some inflammatory etiologies that masquerade as typical IOIS can be vision or life threatening, it is important to consider these diagnoses. Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune process that can affect the eye and visual system in 20% of individuals. In this idiopathic process, the deposition of pathogenic autoantibodies and immune complexes damage tissues and cells. Some common ocular manifestations of SLE include keratoconjunctivitis sicca, periocular skin lesions, orbital inflammation, retinal hemorrhages and vasculitis, retinal vaso-occlusive disease, iritis, scleritis, optic neuritis and optic neuropathy. One rare clinical entity in the SLE spectrum is panniculitis, also known as lupus erythematosus profundus (LEP), which is a nodular inflammation of adipose tissue. Panniculitis involving orbital structures as the primary presenting symptom of SLE is quite unusual and has only rarely been previously reported in the literature and has not been reported presenting as IOIS. This uncommon presentation can make the diagnosis more difficult. We describe a patient who had presented with ptosis evolving to orbital inflammation, which was consistent with IOIS by laboratory and histologic examinations. The patient later developed extensive panniculitis and a final diagnosis of LEP was made.
