hKas 13-10E: Case report: patient with vision defect
Patient A.B., a 75 year old man, came for an eye examination after several months of
gradually worsening foggy vision in both eyes, in particular for distant vision.
Family history: Mother had good distant vision throughout her life, she needed reading
glasses. Father was near-sighted. He has no brothers and sisters and no children.
Personal history: common infant diseases, appendectomy at 15 years, since his 64 years he
has been treated for hypertension. He smokes 20 cigarettes per day, alcohol use 0.
Eye history: He had good distant vision, he has had reading glasses since he was 45 .
He has newer had an eye injury nor an eye operation.
Current disease: He has had a half-year slowly worsening foggy vision in the right eye,
eventually in the left eye as well. His vision for reading was without difficulty at first, but his
reading glasses recently were not sufficient and he now reads better with weaker glass
correction. Temporarily a monocular diplopia appeared. Patient also complains about
unpleasant glare, especially when driving at night.
Clinical finding: Eye surrounding without any pathology bilaterally, globe motility without
limits in all directions, equal globes position. Anterior segment was without pathological
findings. Pupil reactions were normal. A biomicroscopic examination showed cataract in
central parts of the lens bilaterally. Reflex from an eye ground in retroillumination was
partially darken. There were sporadic opacities in the vitreous body. Ophthalmoscopic finding
of an eye ground corresponded to patient’s age.
Intraocular pressure: rights eye 15 mmHg, lefts eye 17 mmHg.
Subjective investigation: VA
Right eye 5/20 –2,0 D
Left eye
5/15 –1,0 D
Jaeger charts No. 7 +1,0 D
Jaeger charts No. 5 +2,0 D
Perimeter: visual field without any pathologic changes.
Questions:
1. What is the cause of the patientÅ› vision disorder?
2. What type of cataract can be suspected in this case?
3. Which part of the population does this cataract usually affect?
4. Why can the patient read better with weaker glass correction than he used earlier?
5. What therapy would you suggest?
6. What is the vision prediction for the patient with and without therapy?
PF: Pathophysiology of the crystalline lens
PA: Eye tumours
Kas 13-11E: Case report: transient deterioration in vision
Mr. A.D., 65 years old man, visited the Eye department because of sudden vision
deterioration of the left eye.
Family history: parents wore spectacles, mother had strong correction for near and distant
vision, son and daughter healthy, without glasses, wife underwent the retinal operation.
Personal history: no serious illness, no general treatment, problems with prostate gland
recently. Blood pressure 130/85, DM 0, ischaemia 0, normal blood count, neurological
problems 0, hormonal therapy 0.
Eye history: good sight, since he was 25 years old – spectacles for distant vision. From the
age of 40 he wears bifocals. He could see well through the bifocals.
Current disorder: while driving a car in the evening he realized blurred vision of the left
eye, he saw rings round the lights with the left eye, the eye was slightly more sensitive.
Because his wife has been treated in our clinic, he rather came over for investigation.
Clinical finding: Right eye: all finding, except the shallower anterior chamber, was normal.
Left eye: mild passive conjunctival hyperaemia, corneal stroma oedema was damping out,
shallow anterior chamber, slightly wider reactive pupil, normal eye ground.
Gonioscopy: Right eye- narrow beaked chamber angle, grade 1, ciliary border concave. Left
eye- markedly concave ciliary border, angle differentiable with difficulty, grade 0-1, gently
slackening with pressure. Intraocular pressure: right eye 19 mmHg, left eye 45 mmHg.
Subjective investigation: VA right eye 6/6 +2,0D Jaeger 1 +5,0D
left eye
6/9 +3,0D Jaeger 1 +6,0D
Perimeter- visual field examination: (one week later) physiological finding bilaterally.
Questions:
1. What was the cause of vision disorder?
2. About what kind of glaucoma is the case report?
3. Which eyes are predisposed to that kind of glaucoma, what can cause the elevation of
intraocular pressure?
4. Why did we not find pathological changes of optic nerve head and in the visual field?
5. Which attack can be caused by passing over several attacks of this kind without therapy?
6. What are the local and general signs in acute congestive angle-closure glaucoma?
PF: The factors influencing intraocular pressure

Kas 13-12E: Case report: patient with refractive error
Mr K.R., 11 years old pupil, appeared in eye examination for foggy vision for distance.
Family history: Mother has worn spectacles for distance since her 13. Father has no
problems with eyes and no dioptric correction.
Personal history: common infant’s diseases, as 9 years old he had an bike injury followed
with fracture of the right leg.
Eye history: He had good vision and no spectacles until now.
Recently he realized worse vision in the school, when looking at blackboard. He was changed
into the front desk. But he had the same problems with vision also from this place a few
months later. Mother tells, that he has problems during watching a TV and looking for
distance.
He has no problems with near vision.
Clinical finding: Globe motility without limits by all directions, equal globes position.
Cornea bilaterally smooth, glossy, clear, anterior chamber slightly deeper, pupil round, in the
center, pupilar reactions normal, Iris calm, clear optic media. Fundus is without any
pathological findings.
Subjective investigation: VA
Right eye 5/15 nat.
Jaeger charts No. 1 nat.
Left eye
5/10 nat.
Jaeger charts No. 1 nat.
Questions:
1. What is the most likely cause of the boy difficulties?
2. Try to explain the etiology and optic status of the eye in this refractive error.
3. Do we need any further examination for the differential diagnose? If yes, which?
4. What kind of spectacle lenses do we correct this refractive error?
Are they: a.) Converging lenses
b.) Diverging lenses
c.) Cylindrical lenses
5. Is there other possibility to correct the error than the spectacles?
PF: Refractive media – basis of pathophysiology.

Kas 13-14E: A case-report: what forces the patient to visit eye doctor
A patient E.F., 65 year old pensioner, referred for cutting, pain and deteriorated vision on the
left eye.
Family history: mother had diabetes in her old age, died in 76 years of stroke, father died of
heart infarction in 72 years. Sister has hypertension.
Personal history: three years ago (for dysuria) incidentally diagnosed diabetes, glycemia at
that time 20,0mmol/l. Treated with oral antidiabetics, she doesn´t follow a strict diet,
glycemia from 9 to 12, sometimes even 15,0.
Eye history: previously no eye problems, bad vision of her right eye in last years but she
didn´t mind, she can still read with her left eye. She doesn´t go to any eye check-ups.
Complaints: Since yesterday her eye is red, painful and vision is worse. She informed us
about contact with branch of tree.
Ophthalmologic examination:
RE VA (right eye visual acuity): HM (hand movement), certain light perception
LE VA (left eye visual acuity): 6/24 uncorr. VA: 6/12 with +1,0 D. Jaeger No.5 with +4,0 D.
IOP (intraocular pressure): RE 23mmHg,
LE 17mm Hg
RE: Eye is quiet, slightly divergent, motility normal, outer segment normal, pupil is 2,5 mm,
photoreaction +, cortex lens opacifications, red reflex is dead, blurred due to hemorrhage,
therefore other retinal examination is impossible.
LE: Partial blefarospasm, conjuctiva is irritated, eye motility is normal, corneal defect epitelial abrasion coloured by fluorescein in central part. Anterior chamber is deep, content
without changes, iris is atrophic and quiet, pupil photoreaction +, lens with opacification in
periferal cortex, red reflex +. Fundus: optic disc well demarcated, with small new vessels.
Arteries narrow, nasally obliterated, veins irregular, tufts of new vessels nasally. More new
vessels are in the upper and lower temporal region. Many microaneurysms, dot and blot
hemorrhages. Cotton-wool patches in all quadrants. Macula thickened, with clusters of
microaneurysms surrounded with hard exudates.
Internal examination: medium obesity, BP 190/100, HR 72/min, varices of lower extremities.
Laboratory tests: SR 15/30, glycemia 15,0, other tests not available.
Questions:
1. What forced her finally to visit eye doctor?
2. What is the principal eye diagnosis, what is its etiopathogenesis, what is its probable
duration and the
control of the disease? Think about the relation to the patient´s history, the education of the patient and other
circumstances.
3. Assess the finding on the left eye.
4. Evaluate the findings on the right eye, why eye is nearly blind?
5. Why the right eye is in divergent position?
6. Summarize the case report and formulate principles of co-operation between the patient and his attending
physicians.
